What will be valuable assets in the future?
The value of an asset is related to its scarcity. Expertise, which will become democratized due to AI, will not be scarce.
Assets that perform a function and can be reused will be valuable. Your abilities when they are focused on creating an outcome will be valuable.
Land will always be valuable as there is a limited amount available.
Money and investments will always be valuable.
When you are young, the more growing assets you can create including land and investments the more freedom you will have later in life. Freedom is the ultimate asset. When you are free you have greater opportunity to create value.
